Hello @tristancarax I understand completely. I knew someone once in that situation. I didn't even scratch the surface of what really could happen in these type of situations because it's so gross and heartbreaking. But the fact is it's an illness that requires therapy. Family usually doesn't know how to help and only makes the family member withdraw even further and ban them from coming around.
In worse case scenarios, animal life is living inside the appliances, including the refrigerators, cupboards, stove, and cabinets. That's what makes people sick.
My mom was a mini hoarder. But as much as she brought in, we gave away. And she didn't even miss it. It was a never-ending revolving door. I've seen worse cases than hers. At least, it didn't involve trash. Just junk trinkets, and 10 items of each.
